Taking the packaging industry as an example, the emergence of stretch film is the change of packaging in many industries. The use of stretch film can reduce the labor intensity of workers, improve packaging efficiency and packaging grade. The application of the wrapping film is very wide, the wrapping of the wrapping film has to be stretched, and the stretching form of the tray mechanical packaging has main stretching and pre-stretching. Stretch film can be divided into hand-wound film and machine wrap film, which can be widely used in centralized packaging of various goods.

For all kinds of relatively large finished packaging, such as plates, foods, and medicines, they can be fast-packed by machine-wound film and then transported through trays, thereby reducing labor costs for workers and increasing packaging speed. The packaging grade has been improved, so the wrapping film is the choice of more manufacturers.

Conventional environmentally friendly PVC wrapping film packaging aluminum profiles and plastic steel sheets are the most suitable, but some customers have feedback that the phenomenon of color disappearing after wrapping aluminum-plastic doors and windows, and then let customers send aluminum plastic samples to confirm.

After the experiment was carried out by the manufacturer, the reason was that a paint was sprayed on the aluminum-plastic panel, and the phenomenon of coloration occurred with the chemical reaction of the PVC in the PVC wound film. After finding the problem, the same customer It is recommended to use a PE stretch wrap film, and no such phenomenon occurs when it is put into production.

Therefore, in some conventional product packaging, it can be recommended to the customer for normal use. For some customers, the material is not very well understood. It is best to send the sample to us for testing and recommend a suitable packaging material.
